Answer 1

You can call async task on text click inside Custom adapter

localViewholder.quote.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
               new GetBuyingReqList.execute();
            }
        });

and make GetBuyingReqList class private to public

Answer 2

put below code where u want

GetBuyingReqList getBuyingReqList = new GetBuyingReqList ();
getBuyingReqList .execute();

Answer 3

This might not be the correct approach of coding ,where in you have all the asyncs in one activity.

But to achieve what you want you can use the context that you pass in the adapter like this:

((YourActivityYouArePassing)mContext).someMethod();

the activity's context must be the same as the one you are using for type casting, and someMethod() should be a method declared inside the activity with public keyword.

in someMethod() you could then call your async task like:

public void someMethod() {
     new AsyncClass().execute();
}

EDIT:

The onClick will look like this in the adapter

localViewholder.quote.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            /*
             * HERE I WANT TO CALL "GETqUOTElIST" ASYNCTASK OF MY ACTIVITY/////!!!!!!!
             */
             ((YourActivityYouArePassing)mContext).someMethod();
        }
    });

Hope that helps!!

Answer 4

Possible duplicate How to Call AsyncTask from Adapter class?

found these answers

1. move your adapter class inside your activity class and make adapter class as inner class.so you have access for calling Asynctask in adapter

2. Remove AsyncTask Inner class from activity class and Make AsyncTask as a separate class (put it in your package). After that you can call like this "new Asynctask().execute();" from any where

3. what i did... i sent an instance of the activity to the adapter while initializing, then i called a method at the activity by activity.method() and this method calls the AsyncTask
